Going to bed for a 8:45 am alarm

Asleep by 11:30 pm — 6 full sleep cycles, about 9 hours
Asleep by 1:00 am — 5 full sleep cycles, about 7 hours
Asleep by 2:30 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

Online alarm clock for 8:45 am

Watching the sets while you wait for 8:45 am lets you squeeze in a morning surf without drifting into work time. The alarm marks the moment to catch the last wave, paddle back and start packing the board. That leaves the remaining quarter-hour before 9:00 am for getting off the sand and changing for your shift.

With waves, wind and beach chatter around you, an alarm that seems loud indoors may disappear into the background. Set the volume above the surrounding noise and place the phone where its speaker is not buried under a towel or clothes. A quick sound check before entering the water shows whether you can hear the chosen tone from nearby. If the browser page is closed or your phone goes to sleep, the alarm will not sound, which could let the surf run into your shift.

Coming ashore at this early hour is easier when breakfast does not become another job before 8:45 am. Water and a small, easy-to-carry snack can be ready with your keys and work clothes, while a bigger brekkie can wait until the board is secured. Keep the drink away from the phone, and allow enough time to rinse off salt and sand before heading to work.

Common questions

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
